Personal Thoughts:

I "completed" this for Fanime 2009 - but I was extremely unhappy with the way the top turned out. I finally managed to redo the top for Fanime 2010! Now that it's fixed this costume may now be my favorite over Myu Uranus :3. It's surprisingly comfortable for a ballgown (including a corset) and not that difficult to move around in.
